blurring是什么意思？

A blur is a shape or area which you cannot see clearly because it has no distinct outline or because it is moving very fast.

When a thing blurs or when something blurs it, you cannot see it clearly because its edges are no longer distinct.

If something blurs an idea or a distinction between things, that idea or distinction no longer seems clear.

If your vision blurs, or if something blurs it, you cannot see things clearly.
